In the 'Mountain Name' section it speaks of 'Fujiyama', which is incorrect if you are going to use the japanese word. The character for mountain has two readings, and when it is used as a suffix it is read as 'san'. Thus 'Fuji-san' is the correct term to use when referring to this Japanese mountain.
A couple amendments to the 7 mile hike described above:
Fuji Road (aka 5894) is just past milepost 57 (between 57 and 58), not 56. You'll see the 5894 sign immediately; the Fuji Mtn Road sign is 50-100 ft up the road. In about 1/4 mile, the road forks - take the left fork (there is a road closed gate). The road is barely okay for passenger car of average clearance.
Based on our experience, I think the hike is ~10 miles (including spur), not 7. We took the spur trail from the north side of the parking lot at the end of 5894, which joins the main trail right near the cutoff to Jo Ann Lake.
The spur trail was not well maintained, but was easy to follow with frequent blazes (high in the tree, presumably because these trails are oriented to x-country skiers).
The hike was a pleasant walk in the forest with generally gentle grade. Fuji Mountain doesn't really reveal its view until the last few hundred yards. If you are mostly interested in the view, do the short trail. If you want a long hike, I'd probably use the proper Waldo Lake starting point. I'm not sure the middle option we did has much to recommend it, given it's about as long and not as easy to get to/follow.
